CABLE-TERMINAL.

Specification of Letters Patent.

Application filed August 11, 1913. Serial No. 784,020.

To all whom it may concern Be it known that I, FRANK B. Coon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cable-Terminals, of which the following is a specification.

This invention refers to terminals for cables, such terminals being provided with means for distributing the various conductors of the cables and for protecting the conductors against excessive currents. I With cable terminals as heretofore constructed the work of distributing the conductors has been done after the terminal was mounted upon the pole or other suport. p One of" the objects of this invention is to avoid the inconvenience and tediousness attending the distribution of the wires by the lineman while. on the pole, by providing a removably mounted distributing section which is held in place by quickly operable means so as to permit easy removal of said section, whereby the wires may be (118- tributed in the shop or in any other convenient place.

It is frequently the case that a company installing cable terminals desires, for reasons of economy, to dispense with protection for the individual conductors until some future time. Heretofore there has been no construction of cable terminal which permitted of a convenient change from an unprotected to a protected condition of the circuits.

One of the objects of this invention is to provide a cable terminal of such nature that fuses and lightning arrester may be conveniently installed thereon at any time and without alteration of the terminal. Cable terminals have heretofore been mounted upon the pole in such a manner that the portion of the cable entering the terminal was readily accessible to the lineman, and

constituted a temptation to him to use the cable as a hand-hold in ascending or descending the pole, with consequent liability of straining and injuring the electrical connections.

It is one of the objects of this invention to mount or brace the terminal in such a the cable as a hand-hold.

' is an elevation of a cable terminal showing the improved method of mounting the terminal. Fig. 2 is a view illustrating the terminal in place upon a pole, the inclosing casing being in section. Fig. 3 is a fragmental sectional detail. Fig. 4 is a fragmental underside view. Fig. 5 is a horizontal sectional view taken in the plane of dotted line 5 of Fig. 2. Fig. 6 is a fragmental sectional view of the terminal. Fig. 7 is a plan view of a removable section of the terminal. Figs. 8 and 9 are sectional detail views.

In the embodiment herein shown of the invention, the terminal comprises a sheetmetal base plate 1, a plurality of vertical radial frame-bars 2 fixed at their lower ends to the base plate, an annular vertical ring 3, connected to the inner edges of the radial bars 2, and located relatively close to the base plate, and an annular vertical ring 4 connected to the inner edges of the bars 2 and located above the ring 3. While these parts may be constructed in various ways, it is advantageous to form each frame bar 2 of two metal plates 2 secured together .in a suitable way, as by clenched lugs 2 (Fig. 8). The adjacent plates 2 of every two adjacent bars 2 are formed integral with a section of'the ring 3 and a section of the ring 4.. Thus it will be understood that each of the rings 3 and 4 consists of a plurality of sections, each section extending between and integrally connecting a pair of the plates 2*.

The terminal further comprises a removable distributing section which, in the pres ent embodiment, consists of a cup-shaped element 5 adapted to fit between the upper ends of the frame bars 2 and rest upon the Fatented Nov. 314, 191 .6.

ring 4. Fixed to the bottom of the cup 5 I is a nozzle 6, through which the conductors of a cable may be passed into the cup. The

-. nozzle 6 extends throughan aperture 7 in 55 the base plate 1 and is of sufficient length to permit of conveniently attaching a cable sheath thereto. If desired, the nozzle 6 may be of the well-known self-soldering type.

Around the outer side. of the cup 5 is a series of cable-conductor terminals. These terminals may be of various forms, that herein shown comprising hollow connecting posts 8 which may be similar tothose fully described in Patent No- 897062, granted to is me on 'August 25, 1908. Associated with each connecting post 8 is a spring member 9 and a grounding spring member 10. ,The posts 8 are insulated from the cup 5 and the spring members 10, but are electrically con nected-to the spring members 9. The cup 5 is provided with a flanged cover 11, a gasket 12 preferably. being interposed between the cup and its cover. The cup 5 may. be secured in place on its seat a by any-suitable means. That herein shown comprises a-disk 13 having slots 14 in its periphery-to receive the inner edges of the frame bars 2, the latter having notches 15 therein. After the disk 13 has been turned to'carry the slots 14 oiit of register with the frame bars 2, as shown in Fig. 5, thereby placing the periphery of the disk in the notches 15. 1 In the center of the disk is a clamping screw 16 arranged to bear against the cover 11 and thus clamp the latter in place.

In order accurately 'to position the cup 5' ter properly with cooperating members to be later. described, said cup may be provided with pairs of lugs 5 (Fig.8) adapted to lie at opposite sides of the frame bars 2. I

On the outer side of the ring 3 is a series and for connecting in circuit the jumper wires 17 These devices may be ofany suit "able construction; herein I have shown two forms, one adapted .for single-party lines meansof bolts 19.

In the present embodiment, each pluralparty terminal comprises a block 20 of insulating material, said block having a locating stud 21 adapted to enter one of the holes 6 provided forthe bolts 19-, and being secured to the ring 3 by means of a bolt 22. There is'a series of holes for the reception of the bolts 19 and 22 and'the studs 21, so that single-party or. plural-party terminals may be mounted on the ring 3 at any desired placed on topof the cover-11, said disk is- 'on its seat so that the members 9 shall regisof devices for supporting circuit-protectors and the other for plural-party lines. The

The devices 18 are secured to the ring 3 by' point and in any desired order. The pluralparty terminals further comprise members 23 adapted .to receive fuses or direct-connection wires. The jumper wires extend through openings 24 in the base plate 1.

The cable terminal may be mounted upon a pole or other support by means of a bracket 25 of any suitable character, and two braces 26, said braces extending at opposite sides of the nozzle 6, and extending 111 an inclined direction between the base plate 1 and the support. The parts mounted upon the base plate are covered by a casing 27 which rests removably on the base plate and is held against lateral dispacement by the frame bars 2.

be filled with a suitable insulating compound (not shown). The lineman then places the cup upon its seat 4, and splices the ends of the conductors'w, which protrude from the lower end of the nozzle 6 to the ends of the conductors ofthe cable :20. The cable sheath and the nozzle 6 are then united in anysuitable way, as. by a wipe joint 3 It will be seen that my invention obviates the necessity of distributing the cable wires after the terminal is mounted on the pole,

as this work may be done at any convenient time and place. Moreover, in case of trouble with any ofthe connections onthe cup 5, the lineman need not search out the: I

source of trouble while at the terminal, but

may cut the cable, remove the cup, SllbStl-j' tut'e another and connect the wires of. the

Y new cup to the wires of the cable.

he elements 9, l8 and 23 are ada ted to I support direct-connector rods 0: or ses b. Carbon lightning arresters 0 may or maynot be placed between the springs 9and 10, as considerations of economy may dictate. Thus it will be seen that the. company owning the terminal may, if desired," dispense "T with circuit-protective devicesfor' a period of time, and may later provide fuses b or lightning arresters c'or both, without making any alterations of the terminal. Single-- party and plural-party terminals may be used upon the cable terminal in any desired combination. The .braces 26 extend at opposite sides of and in the 'same general direction as, the" cable a and the nozzle 6, and thus serve as guards for said'cable and nozzle and prevent the lineman from using the cable or nozzle as a hand-hold.

In the manufacture of the terminal, the frame sections formed of the partsQ and the integral sections of the rings 3 and 4 may be assembled in greater or less numbers to produce terminals of greater or less diameter. It will be understood that the curvature of the rings 3 and 4 and the angle betweensaid rings and the plates 2 may be readily altered to conform to the diameter of the terminal to be constructed.
